To analyze the trends in international medical graduates (IMGs) matching into diagnostic radiology residency programs in the United States (US).The National Resident Match Program data was accessed for years 2005-2020 and diagnostic radiology residency-specific data was extracted for US MD, osteopathic (DO), and IMG applicants. IMGs were categorized into US-citizen IMGs and non-US citizen IMGs per the National Residency Match Program. Variables collected for each year included the number of positions, number of applicants in each group, positions filled/unfilled, and fill rate of each group. Additional data for some years included USMLE Step 1 score, United States Medical Licensing Examination (USMLE) Step 2 clinical knowledge (CK) score, number of research experiences, number of abstracts/publications, and additional degrees obtained. Trends were analyzed using simple linear regression model and p value0.05 was considered significant.The number of diagnostic radiology residency programs increased from 203 (2006) to 212 (2020). The total number of diagnostic radiology residency positions increased from 1011 (2006) to 1113 (2020), with the peak of 1145 in 2014. The overall "match rate," that is, proportion of positions filled to positions available, increased from 96.4% (2006) to 97.3% (2020), with a brief decline to 86.7% in 2015. Among the filled positions, the proportion filled by US medical school graduates significantly declined from 89.7% (2006) to 69.2% (2020) (p0.001), and the proportion of positions filled by osteopathic seniors and graduates significantly increased from 2.2% (2006) to 15.1% (2020; p0.001). The proportion of US IMGs increased from 3.2% (2006) to 5.4% (2020), while the proportion of non-US IMGs increased from 4.4% (2006) to 9.4% (2020), with overall IMG match rate increased significantly from 7.6% to 14.9% (p = 0.009). The mean Step 1 scores of US IMGs and non-US IMGs were 238 and 237.3, and the mean Step 2 CK scores were 241.67 and 241, respectively. Cumulatively over the study period, a total of 736 US IMGs and 1051 non-US IMGs have matched into diagnostic radiology residency.There is an increasing proportion of IMGs, especially the non-US citizen IMGs, matching into US radiology residency programs in the last decade. Diagnostic radiology remains a competitive specialty evidenced by average USMLE scores higher than national average and research experiences of matched candidates.

We are in the midst of an evolving educational revolution. Use of digital devices such as smart phones and tablet computers is rapidly increasing among radiologists who now regularly use them for medical, technical, and administrative tasks. These electronic tools provide a wide array of new tools to the radiologists allowing for faster, more simplified, and widespread distribution of educational material. The utility, future potential, and limitations of some these powerful tools are discussed in this article.

Increasing use of smartphones and handheld computers is accompanied by a rapid growth in the other related industries. Electronic books have revolutionized the centuries-old conventional books and magazines markets and have simplified publishing by reducing the cost and processing time required to create and distribute any given book. We are now able to read, review, store, and share various types of documents via several electronic tools, many of which are available free of charge. Additionally, this electronic revolution has resulted in an explosion of readily available Internet-based educational resources for the residents and has paved the path for educators to reach out to a larger and more diverse student population.

To determine the impact of incremental increases in computed tomography (CT) image noise on detection of low-contrast hypodense liver lesions.We studied 50 CT examinations acquired at image noise index (NI) of 15 and hypodense liver lesions and 50 examinations with no lesions. Validation of a noise addition tool to be used in the evaluation of the CT examinations was performed with a liver phantom. Using this tool, three 100-image sets were assembled: an NI of 17.4 (simulating 75% of the original patient radiation dose), 21.2 (simulating 50% dose), and 29.7 (simulating 25%). Three readers scored certainty of lesion presence using a five-point Likert scale.For original images (NI 15) plus images with NI of 17.4 and 21.2, sensitivity was90% threshold (range, 95%-98%). For images with NI of 29.7, sensitivity was just below the threshold (89%). Reader Az values for receiver operating characteristic curves were good for original, NI 17.4, and NI 21.2 images (0.976, 0.973, and 0.96, respectively). For NI of 29.7, the Az decreased to 0.913. Detection sensitivity was90% for both lesion size10 mm (85%) and lesion-to-liver contrast60 Hounsfield units (85%) only at NI 29.7.For low-contrast lesion detection in liver CT, image noise can be increased up to NI 21.2 (a 50% patient radiation dose reduction) without substantial reduction in sensitivity.
